The machine work on the hub itself was outstanding and the shaft ran true. However as usual I found one of the supplied shaft support bearings was shot right off the start. When I unpacked it the bearing was already catchy as it rolled. So I replaced them both with ceramics and now the tail is perfect! I would have given this a 5 star had the bearings been a better quality. As is I still recommend this highly. Just be aware the bearings themselves will probably be hit and miss.
